Poundal/square Foot
The poundal per square foot (pdl/ft^2) is a unit of pressure representing the force of one poundal applied over an area of one square foot.
History/Origin
The poundal is an imperial unit of force introduced in the 19th century as part of the foot-pound-second system, primarily used in engineering contexts. The unit pdl/ft^2 was used historically in mechanical and civil engineering to measure pressure but has largely been replaced by SI units.
Current Use
The poundal per square foot is rarely used in modern practice, having been largely replaced by the pascal (Pa) in scientific and engineering applications. It may still appear in legacy systems or specific regional engineering contexts.
Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
